This is from a friend of mine who has done tons of show worthy jobs and its by far the easiest with best results Ive used.
"I now start by removing any heavy powder coating (if there is any) with aircraft paint stripper, if the exterior casting is really rough such as the upper intake I’ll start sanding w/ 80 first but most pieces I’ll start my sanding with 100 grit sandpaper and then move up to 150 or 180 grit and then 220 grit sandpaper.
I’ll then move to a Ventilated Flap buffing wheel with Emery compound which does all the work of 320 through 600 grit sandpaper or more, and then I’ll buff with the Tripoli with one Spiral Sewn buffing wheel and polish with White Rouge on a different a Spiral Sewn buffing wheel with an electric drill.
Eastwood carries the Ventilated flap #13155 and Emery Compound part # 13134
I’m not saying its right or wrong, but I’ve never wet sanded a part because I didn’t like dealing with the mess, however I do use wet/dry sand paper though.
If you choose to buy the eastwood kit Part # 13149 which I would highly recommend,
the kit come with everything you would need to sand with in those hard to reach areas, besides the compounds to buff and polish with.
I would suggest and that’s all it is a suggestion if you decide to buy from eastwood these are the other items I would purchase."
